It could be a story set in an alternate magical world where a strange magic has made Hermione pregnant with a 'concept' rather than a physical baby. For example, she might be pregnant with the idea of unity between different magical races. Harry and Hermione then have to figure out how to give birth to this concept, which involves going on a journey across the magical world, meeting different races and learning about their cultures in order to make the idea a reality.
One possible plotline could be a magical experiment gone wrong. Maybe they were working on a spell to enhance fertility in magical creatures, but something backfired and Hermione ended up with some symptoms that made it seem like she was pregnant. Harry and Hermione then have to find a way to reverse the spell without anyone else finding out, leading to a lot of sneaking around and problem - solving.
One possible plotline could be that they are on a dangerous mission, and a magical mishap causes this situation. Then they have to deal with the social and family reactions in the wizarding world, which could be full of prejudice and confusion. Another could be that it's a result of a new, experimental magic they were trying out for a good cause, and now they have to figure out how to move forward with their friendship and their responsibilities.
One possible plot twist could be that it was all a misunderstanding. Maybe there was a spell that made it seem like Lily was pregnant, but in reality, it was a false alarm. Another twist could be that it was part of a prophecy or a magical plan that was misinterpreted. Instead of a romantic or sexual relationship, it could be a way to save the wizarding world in a very unexpected way.
A possible non - adult - themed plot could be that Ginny is trying to help Oliver with some personal issues he's having. She's being a good friend, but rumors start spreading in Hogwarts that she's cheating on Harry. Harry initially believes the rumors, but as he investigates further, he realizes that Ginny was just being kind. This leads to a story about friendship, love, and not believing everything you hear.
One possible plotline could be that they initially panic but then decide to make the best of it. They might start preparing for the baby by gathering magical baby items and getting advice from their friends. Another could be that they face some sort of prejudice in the wizarding world because of their relationship, but they overcome it together.
One possible plotline could be a misunderstanding. Maybe Annabeth is seen spending a lot of time with Nico because he needs her help with something, like understanding some ancient prophecy. Percy misinterprets this as something more and there is a rift in their relationship that they have to work through.
Yes, there are plenty of non - adult - themed 'Harry Hermione' fanfics. You can find them on various fanfic platforms like FanFiction.net. These fanfics often focus on their adventures at Hogwarts, their friendship, or how they work together to solve mysteries in the wizarding world.
Perhaps Harry Brands is an outsider in the wizarding world, and Hermione takes it upon herself to help him fit in. Their relationship develops as they face various challenges together. The 'Lemon' aspect could be added as a plot device where they encounter a problem that seems insurmountable at first, like a cursed object or a powerful dark magic that has a 'lemony' or bitter quality to it. This forces them to rely on each other more and their bond grows stronger as a result.
One possible plotline could be that Harry says something unkind to Hermione during a heated argument about a school project. This makes Hermione feel betrayed and sad. But later, Harry realizes his mistake and tries to make it up to her.
One possible plotline could be a time - travel or alternate - reality scenario. For example, in an alternate universe where the relationships between characters are different, Snape and Hermione could have a relationship that leads to her getting pregnant. The story could then focus on how they deal with the consequences in that different world, perhaps facing opposition from others due to their age or social differences within the wizarding community.
Another possibility is that they are in a magical academy where Draco is a prefect and Harry is constantly getting into minor mischief. Draco has had enough and spanks Harry as a disciplinary measure. But this then leads to a series of events where Harry and Draco start to see each other in a different light, and they end up becoming friends or at least learning to co - operate better.
